Hi,everyone,
I am develop a device driver on our custom PPC823 board,the board has
linux running on it and everything works well.The device is infact a 8bit
fifo,I use CS5 to select it and read data from it,the Address which is selected
by CS5 is begin at 0xfff00000.I use ioremap( ) function to read data from the
address 0xfff00000,but kernel panic always occured.Does anyone can help me?Any
comments would be appreciated.
Thanks,
Derek
